BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to target traps for use with reality-based methods of target training, as well as shooting skill development through the use of simulation or marking round firearms.

2. Description of the Related Art

Generally, shooting skill development and law enforcement/counter terrorism tactics have advanced through the use of paintball, simulation and marking round weaponry. The use of targets in such activities is a critical component in such activities. Traditional targets are usually a paper product which pellets penetrate easily. The targets are supported by a trap, which captures the round to prevent damaging the surrounding area. Placement of targets is limited to places where a target can be supported, as well as what is behind the target which could be damaged as the pellet or marking round passes through. However, the cost of new pellets and marking rounds over time becomes a limiting factor in the volume of shooting and training that occurs. Additionally, the cleanup of training areas after a training exercise has been completed is consuming and tedious work. Conventional target traps are difficult to clean or are intended as a single use product, which although suitable for recreational use, do not lend themselves to high volume use.

Thus, there is a need for an improved target trap.

DETAILED DESCRIPTION

FIG. 1 depicts one embodiment of a target trap 100 mounted on a stand 102 (shown in phantom) that supports a target 104 (also shown in phantom). Generally, the target trap 100 is suitable for capturing and retaining pellets fired at the target 104. In the embodiment shown, the target trap 100 includes a frame assembly 106, a strike panel 108, a face panel 110, and an optional target support 112 that is utilized with clips 114 to secure the target 104 to the frame assembly 106. While the below description refers to “pellets”, it is understood that the target trap 100 is suitable for capturing and retaining many projectiles, including but not limited to, airsoft pellets, plastic pellets, lead pellets, BBs, marking rounds, paintballs, and the like.

The frame assembly 106 houses the strike panel 108 and the face panel 110 and collects pellets entering the trap 100. As shown in FIG. 1, the frame assembly 106 has a front 136 and a back 138, and includes a bottom wall 120, and sidewalls 116, 118. The front 136 includes an opening 134 defined between the sidewalls 116, 118 that allows for pellets fired at the target trap 100 to pass into the target trap 100. The face panel 110 is retained between the sidewalls 116, 118 and generally serves as an initial energy absorbing surface for pellets fired at the target trap 100 and prevents pellets from ricocheting out of the trap 100. The front panel 110 is positioned proximate to the opening 134 at the front 136 of the frame assembly. The strike panel 108 is retained between the sidewalls 116, 118 and absorbs the projectile energy of the fired pellets after the pellets have passed through the face panel 110. The strike panel 108 is positioned proximate to the back 138 of the frame assembly 106. The frame assembly 106 may optionally include a back wall 122 coupled to the sidewalls 116, 118 in the back 138 of the frame assembly 106 and an optional lid 124 disposed on top of the sidewalls 116, 118. As shown, the optional lid 124 may be a box top having a peripheral down turned flange configured to fit over the upper edges of the sidewalls 116, 118. In another embodiment, the lid 124 may be a flat panel hinged, or similarly pivotally coupled, to a sidewall 116 or 118 to selectively close the frame assembly 106.

The frame assembly 106 may be formed from a lightweight material durable enough to withstand environmental and projectile effects. For example, the trap 100 may be water resistant to allow outdoor use and cleaning. In one embodiment, the frame assembly 106 is fabricated from corrugated cardboard or corrugated plastic. In an alternative embodiment, the frame assembly 106 may be formed from aluminum, cardboard, wood or other suitable sheet material. The target support 112 may be comprised of a metal or plastic rod suitable for supporting the target. The components of the frame assembly 106, for example, the sidewalls 116, 118, and bottom wall 120, may be assembled using welds, adhesives, screws, rivets, glue, or any other suitable fastening means. It is also contemplated that the sidewalls 116, 118, and bottom wall 120 may be fabricated from a single strip of material.

According to one embodiment, the strike panel 108 may be a consumable item that may be replaced within the frame assembly 106 when necessary. The strike panel 108 is fabricated from a material suitable for dissipating the energy of projectiles (e.g., pellets) while preventing the projectiles from penetrating the strike panel itself. In one embodiment, the material of the strike panel 108 should be suitable for absorbing 1-2 joules of energy from the projectiles without complete penetration of the strike panel 108. Additionally, the material of the strike panel 108 may be selected to have compressible properties such that it decelerates projectiles in a manner that that substantially prevents deformation of the projectiles themselves. In one embodiment, the strike panel 108 may be made of corrugated plastic of a suitable thickness. As an example, 4 mm thick corrugated plastic may be used. In alternative embodiment, laminated foam may be utilized. In embodiments where the frame assembly 106 and strike panel 108 are both made of corrugated material, the strike panel 108 may be oriented within the frame assembly 106 such that the fluting of the corrugated material of the strike panel 108 is perpendicular to the fluting of the corrugated material of the sidewalls 116, 118 to increase the rigidity, durability and life of the strike panel 108.

The face panel 110 is a consumable item that is replaced within the frame assembly 106 as necessary. The face panel 110 may be made of a material suitable for initialing slowing the velocity of projectiles entering the target trap 100 and preventing projectiles from ricocheting out of the trap 100 back through the face panel 110 after impacting the strike panel 108. The material utilized for the face panel 110 may be selected to have properties that permit the projectile to pierce the face panel 110 without deforming the projectile itself. In one embodiment, the face panel 110 may be fabricated from corrugated cardboard or other suitable material.

The target trap 100 includes at least one alignment feature that maintains the strike panel 108 and the face panel 110 in a spaced-apart relation. In the embodiment shown in FIG. 1, the sidewalls 116, 118 the alignment feature is a back channel 126 that defines a back slot 128 for retaining the strike panel 108. The sidewalls 116, 118 may optionally include a front channel 130 which defines a front slot 132 which functions as an alignment feature for retaining the face panel 110. The channels 126, 130 may be configured as an integral part of the sidewalls 116, 118, or may be a separate C-channel, L-channel, or any other member coupled to the sidewalls 116, 188 that can define a slot for retaining and aligning one of the panels 108, 110 in an orientation substantially parallel with the plane of the opening 134 and perpendicular to the sidewalls 116, 118. In an alternative embodiment, the frame assembly 106 may not include a channel. Instead, the feature that maintains the panels in a spaced-apart relation may be integral to the strike panel 108 or the face panel 110 itself, as further discussed below in relation to FIG. 3. The slots 128, 130, being open to the top of the trap 100, allow for quick and easy replacement of the panels 108, 110 with little interruption of training sessions.

As shown in FIG. 1, the front of the sidewalls 116, 118 includes front lips 140 and back lips 142. In one embodiment, the channels 126, 130 may be positioned proximate to, or abutting, the front lips 140 and the back lips 142. Mounting holes 144, 146 may be formed through the front lips 140 for supporting the target support 112 (as discussed in detail further below).

FIG. 2 depicts a top view of the frame assembly 106 illustrating the strike panel 108 and the face panel 110 held apart in a space-apart relationship to define an interstitial space 202 between the panels 108, 110. In one embodiment, the strike panel 108 and the face panel 110 may be slidably inserted and/or removed through the top of the frame assembly 106. As shown, the strike panel 108 is held substantially vertical in the back slot 128 defined by the back channel 126. The face panel 110 is held substantially vertically in the front slot 132 defined by the front channel 130 and spaced-apart from the strike panel 108. The interstitial space 202 defined between the strike panel 108 and the face panel 110 may be configured with a suitable distance between the panels 108, 110 to allow for sufficient reduction in velocity to prevent a projectile from bouncing off the strike panel 108 and passing back through the face panel 110. In operation, a pellet 204 fired at the target trap 100 passes through the opening 134, pierces the face panel 110, as shown in phantom in 206, and hits the strike panel 108. The pellet 204 may ricochet off the face panel 110 after hitting the strike panel 108, as shown by arrow 208, before falling into the interstitial space 202, thereby being captured inside the target trap 100.

In one embodiment, the target trap 100 may be configured to absorb the kinetic energy of the pellets 204 without deforming the pellets 204, thereby permitting re-use of the pellets. As discussed above, the materials of the strike and face panels 108,110 may be selected to prevent deformation of the pellets. In one embodiment, the spacing between the strike panel 108 and face panel 110 may be configured to provide adequate space for the deceleration of the pellets 204 within the trap 100. In one specific example, the strike panel 108 and face panel 110 may be held apart at a distance of approximately 1 to 1.5 inches. In another embodiment, the back slot 128 (or other alignment feature retaining the strike panel) may be sized so as to loosely retain the strike panel 108 to more effectively absorb energy of pellets 204. For example, the back slot 128 may be sufficiently wider than a thickness of the strike panel 108 so as to permit the strike panel 108 room to move laterally within the back slot 128 in a direction perpendicular to the plane of the opening 134 upon impact of the pellet 204, thereby increasing the amount of energy absorbed from the pellet 204 upon impact with then strike panel 108 while reducing the opposing forces exerted on the pellet 204 by the strike panel 108 that threaten to deform the pellet. In one embodiment, the back slot 128 is about 0.062 inches wider then the thickness of the strike panel 110.

Generally, it is important that spacing is maintained between the strike panel 108 and the face panel 110. This spacing may be accomplished through a variety of means. For example, alignment features, such as bumps or the channels 126, 130 disposed within or as part of the frame assembly 106 may maintain the strike panel 108 and face panel 110 in the spaced apart position. Alternatively, the strike panel 108 and face panel 110 may include a feature which spaces the panels apart.

For example, in the embodiment depicted in FIG. 3, a strike panel 302 is disposed in the back slot 128 defined by the channel 126 coupled to the sidewalls 116, 118 of the frame assembly 106. The strike panel 302 has a length longer than the height of face panel 110 and a top portion of the strike panel 302 is bent over to form a tab 304 which extends towards and abuts the face panel 110, thereby spacing the face panel 110 away from the strike panel 302 to create an interstitial space 202. As such, the face panel 110 is retained by a front slot 132 defined by an end portion 306 of the tab 304 and a front lip 140 of the frame assembly 106. Alternatively, it is understood that a face panel may be configured to be longer than the strike panel, having its top portion bent over and spacing apart the strike panel. It is also contemplated that the width of one of the strike panel or face panel may be greater than the width of the other, so that at least one side of the wider panel may be bent around to space apart the other panel.

FIG. 4 depicts one embodiment of the frame assembly 106 having a pellet-receiving pocket 402 for collecting pellets 204 within the target trap 100. In the embodiment shown, the pellet-receiving pocket 402 is defined by the sidewalls 116, 118, bottom wall 120, the face panel 110, and strike panel 108. The bottom of the pellet-receiving pocket 402 is defined by the bottom wall 120 of the frame assembly 106, and the front and back of the pellet-receiving pocket 402 are defined by the face panel 110 and strike panel 108, respectively. In an alternative embodiment, the back of the pellet-receiving pocket may be defined by the back wall 122 of the frame assembly 106. In the embodiment depicted in FIG. 4, the bottom wall 120 is a flat plate which allows easy removal of the pellets and cleaning of the trap 100 once the face and strike panels 108, 110 are removed.

FIG. 5A depicts an embodiment of the bottom wall of the frame assembly 106 that is configured as an open tray 502. As shown, the open tray 502 has a bottom 504, three sides 506, and an open front 508 that define a pellet-receiving pocket 402. The open front 508 provides access to the pellet-receiving pocket 402 for retrieval of pellets 204 retained within the target trap 100. In one embodiment, a face panel 110 disposed within the frame assembly 106 proximate to the open front 508 may act as a temporary fourth side of the pellet-receiving pocket 402. As such, when pellets 204 are retrieved from the target trap 100, the face panel 110 may be removed to access the pellets 204 through the open front 508. It is also understood that when the target trap 100 captures marking rounds, paintballs, and other substance-releasing pellets, the open front 508 facilities the cleaning and washing of the open tray 502.

In an alternative embodiment depicted in FIG. 5B, the bottom wall of the frame assembly 106 is in the form of a closed tray 512 having a bottom 504 and four sides 506 (i.e. no open front 508) that define a pellet-receiving pocket 402. The closed tray 512 effectively stores pellets 204 and prevents paint from paintballs from leaking from the pellet-receiving pocket 402 while the trap 100 is in use. In one embodiment, the closed tray 512 may be removed from the frame assembly 106 to facilitate retrieval of pellets 204. In another embodiment, the closed tray 512 may be permanently fastened to the frame assembly 106.

FIG. 6 depicts one embodiment of a back wall 1222 illustrating suspension features 602. Suspension features 602 enable the target trap 100 to be positioned in a variety of locations and orientations. In the embodiment depicted in FIG. 6, the trap 100 has a portrait orientation, with a top 602 being shorted than a side 606, with the top 602 disposed in a vertical orientation and the side 606 in a vertical orientation. Of course, the trap 100 may be rotated for use in a landscape orientation. For example, suspension features 602 may be used to suspend the target trap 100 from various points along the stand 102. As shown, the suspension features 602 may be located on a horizontal top 604 of the back wall 122 and centered along the width of the back wall 122 such that the target trap 100 may be suspended in a substantially vertical (i.e. portrait) orientation. Additional suspension features 602 may be located on the vertical side 606 of the back wall 122, mid-distance along the vertical side 606 such that the target trap 100 may be rotated 90 degrees and suspended in a substantially horizontal (i.e. landscape) orientation. In embodiments of the target trap 100 not having a back wall 122, suspension features 602 may be located on the frame assembly 106 itself (i.e. on one of the components of the frame assembly 106) or on a member attached to the frame assembly 106.

FIGS. 7A and 7B depict various embodiments of a suspension feature 602. In the embodiment shown in FIGS. 6 and 7A, the suspension feature 602 includes a tab 610 having a hole 612 formed therein. The hole 612 may be used as a point of attachment for any suitable means of fastening or suspending the target trap 100, including but not limited to, hooks, line, wire, rods, and clips. As illustrated in FIG. 7A, the tab 610 may project outwards from the back wall 122 to allow for better access to the hole 612. In alternative embodiment shown in FIG. 7B, suspension feature 702 may be in the form of a hook 704 attached to the back wall 122. The hook 704 may be used to suspend the target trap 100 from various points of attachment in different locations. For example, the target trap 100 may be suspended by the hook 704 engaged with holes formed in a stand 102.

Returning to FIG. 1, targets 104 may be suspended from the target trap 100 in a variety of manners. For example, targets 104 may be tacked, taped, held using a temporary adhesive, or secured by any other suitable means. In the embodiment depicted in FIG. 1, a target 104 may be suspended by clips 114 from a target support 112, illustrated as a hanging bar. In one embodiment, the target support 112 may be permanently attached to the frame assembly 106, for example, by weld or mechanical fastening. In another embodiment, the target support 112 is removably attached to the frame assembly 106. As shown in FIG. 1, the target support 112 interfaces with mounting holes 144 proximate to the top of the opposing sidewalls 116, 118 of the frame assembly 106. A pair of mounting holes 146 may also be formed in at least one of the front lips 140. In one embodiment, the spacing between mounting holes 146 is equal to the spacing between mounting holes 144 such that the target support 112 may be used with either sets of mounting holes depending on if the trap 100 is being used in a vertical or horizontal orientation. As such, the target support 112 may be removed from the mounting holes 144 and placed in the mounting holes 146 when the target trap 100 is utilized in a substantially horizontal (i.e., landscape) orientation.

FIG. 8A depicts one embodiment of the target support 112 having an attachment area 802 and mounting ends 804. In one embodiment, the attachment area 802 may include a bar or wire rod. The mounting ends 804 are configured such that the target support 112 is securely supported when the mounting ends 804 are inserted into mounting holes 144 or 146. For example, as shown in FIG. 8B, the mounting ends 804 include an S-turn that engages with the mounting holes 144 and an end portion 806 that abuts the inner wall of the front lip 140 to support the target support 112. The target 104 may be fastened to the attachment area 802 of the target support 112 using clips 114 (such as spring clips).

FIG. 9 depicts a partial view of another embodiment of a target trap 900 have a feature for securing a target 104. The trap 900 is substantially identical to the trap 100 describe above except that the sidewall 116 (or 118) may include a projecting lip 902 that allows attachment of a clip 114 to secure a target 104 when the target trap 900 is utilized in a substantially horizontal position. It is also contemplated that, in those embodiments having an additional channel 130 for retaining the front panel 110, the front lip 140 may be configured to allow attachment of the clip 114 to secure the target 104.

Thus, a target trap has been disclosed which captures and retains pellets fired at a target. The target trap 100 is light weight and weather resistant. The target trap allows for more training activities to be conducted in more locations by reducing the risk of damage to fragile items within the area of use, such as windows and computer screens. The target trap also allows for recovery of pellets and marking rounds for later re-use, reducing the cost of purchasing new pellets and rounds, and facilities the cleaning training areas by storing captured pellets and retaining marking paint within the target trap, thereby improving the operational efficiency of law enforcement and skill shooting training. Moreover, as the trap may be easily cleaned, the trap is beneficial for use with paintballs.
